Amazon’s new Dash Wand has Alexa built right in, and lets you order groceries and other household goods just by scanning a barcode or using your voice. The best part though? It’s basically free.

The Dash Wand will set you back $20 upfront (not bad considering it’s a full-featured Alexa voice assistant), but once you register it, you’ll get a $20 credit in your Amazon account automatically. It’s basically the same value proposition behind Amazon’s $5 dash buttons, but the Wand seems infinitely more useful and flexible.

Plus, if you live in a city with Amazon Prime Fresh, buying the wand will get you a 90 day trial membership, so you can fully immerse yourself in Amazon’s lazy vision of the future.
